Can it be programmed through the Arduino IDE?

I had briefly looked into it back in 2011 and was able to get an Arduino sketch for blinking a LED to work. I had to upload it using the external dfu program since at the time the Arduino IDE did not allow specifying an external programmer device. I'm not familiar with what may currently be possible with the Arduino IDE since that time however.

Plain C using gcc and uploading using dfu-programmer works fine though.
